Description

Technical Field

[0001] This utility model relates to the field of circular agriculture equipment technology, specifically to a circulating agricultural biogas slurry buffer sedimentation tank. Background Technology

[0002] Circular agriculture refers to activities that promote the multi-layered and efficient flow of various agricultural resources within an agricultural system, thereby achieving energy conservation, emission reduction, and increased income, and promoting the sustainable development of modern agriculture and rural areas. In simpler terms, circular agriculture is an agricultural production method that utilizes the principles of material recycling and multi-level material utilization technologies to achieve production with less waste and improve resource utilization efficiency. As an environmentally friendly farming method, circular agriculture has significant social, economic, and ecological benefits.

[0003] Currently, the manure produced by pig farms is used for biogas power generation, but a large amount of biogas residue and biogas slurry are still produced with low utilization rates. Biogas residue and biogas slurry can be used as fertilizer, but generally only for artificial fertilization. When used for large-scale agricultural irrigation, the unfermented biogas residue in the biogas slurry will clog the pipes, making it impossible to achieve sustainable circular agriculture. Therefore, this application proposes a circulating agricultural biogas slurry buffer sedimentation tank. Utility Model Content

[0004] To overcome the problems in the background technology, this utility model provides a circulating agricultural biogas slurry buffer sedimentation tank, which solves the problem that while the manure produced by pig farms is used for biogas power generation, there is still a large amount of biogas residue and biogas slurry with low utilization rate. When used for large-scale agricultural irrigation, the unfermented biogas residue in the biogas slurry will clog the pipes.

[0005] A circulating agricultural biogas slurry buffer sedimentation tank includes a tank body, a first partition, a second partition, a third partition, a filter screen, an inlet pipe, and a drain pipe. The first partition, the second partition, and the third partition are evenly installed in the tank body to divide the tank into multiple buffer zones. The height of the first partition, the second partition, and the third partition decreases sequentially. The filter screen is installed longitudinally on the top of the first partition, the second partition, and the third partition and connected to the tank body. The inlet pipe is connected to the buffer zones separated by the first partition and the second partition. Drain pipes are connected to the buffer zones formed by the second partition, the third partition, and the buffer zones formed by the third partition and the first partition.

[0006] Furthermore, a limiting rod is installed at the center of the pool, and fixing hooks are evenly arranged on the outer wall of the pool. A protective net is installed on the top of the pool through the limiting rod and fixing hooks.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] This invention features partitions 1, 2, and 3, with progressively decreasing heights, dividing the pool into multiple buffer zones. This allows the biogas residue to fully ferment in each buffer zone before flowing into the next, further refining, settling, and fermenting into biogas slurry. This solves the problem that while pig farm manure is used for biogas power generation, a large amount of biogas residue and biogas slurry still has low utilization rates. Furthermore, when used for large-scale agricultural irrigation, the unfermented biogas residue in the biogas slurry can clog pipes. Attached Figure Description

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] This utility model proposes a circulating agricultural biogas slurry buffer sedimentation tank, see reference. Figure 1-3 A circulating agricultural biogas slurry buffer sedimentation tank includes a tank body 1, a first partition 2, a second partition 3, a third partition 4, a filter screen 5, an inlet pipe 6, and an outlet pipe 7. The first partition 2, the second partition 3, and the third partition 4 are evenly installed in the tank body 1, dividing the tank into multiple buffer zones. The height of the first partition 2, the second partition 3, and the third partition 4 decreases sequentially, allowing the biogas residue in the tank to be fully fermented in each buffer zone before flowing into the next buffer zone, thus refining, fully sedimenting, and fermenting the biogas residue into biogas slurry. The filter screen 3 is installed longitudinally at the top of the first partition 2, the second partition 3, and the third partition 4 and connected to the tank body 1, which can filter biogas residue that does not meet the requirements. The inlet pipe 4 is connected to the buffer zones separated by the first partition 2 and the second partition 3, allowing the biogas residue and biogas slurry to enter. The outlet pipe 7 is connected to the buffer zones formed by the second partition 3, the third partition 4, and the first partition 2 for cleaning and drainage.

[0016] See Figure 1-3A limiting rod 11 is installed at the center of the pool body 1, and fixing hooks 12 are evenly arranged on the outer wall of the pool body 1. A protective net 8 is installed on the top of the pool body 1 through the limiting rod 11 and the fixing hooks 12 to prevent impurities in the environment from entering the pool.

[0017] Work process:

[0018] The biogas residue and biogas slurry are discharged into the first buffer zone at regular intervals through the inlet pipe 4. The fermented upper clear liquid enters the next buffer tank through the filter screen 5. Through the full fermentation and filtration of the clear liquid in multiple buffer tanks, the discharged clear liquid meets the standards for pipeline agricultural irrigation.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
